Who is OE manufacturer of HID bulbs?

Philips and Osram are the ones widely used in cars in North America/Europe. (GE is still trying to get their feet into car manufacturers’ budget.) They come with standard 4100K color temperature only. This is the only legal HID bulb color temperature under DOT/ECE regulations. Many projector headlights in upscale vehicles may look like they have higher Kelvin rating, but that is an optical effect.


Does Philips or Osram make HID bulbs with halogen base?

None of the OE companies manufacturer HID bulbs with any halogen type base. This would be an illegal product to sell and use on the street. OE companies value safe products higher than making some quick money now and lawsuits later. The only base they produce is P32-d that will fit into socket of an OEM HID headlamp. As an example, any seller who claims to have a 9006 Philips HID bulb is a scam. This is confusing marketing. At the best, all the seller can offer is a 9006 rebased Philips OEM HID bulb.


What is the difference between D2R and D2S?


What is color shift?

The labeled light color on an HID bulb is an average that it will maintain over 2-3000 hours. After passing around 100-500 hours the phenomenon "color shift" will take place. Color will change slightly from a yellowish tone to a crisper bluer tone. The magnitude of color shift will vary depending on brand, model and rated color. It is a very gradual change and unless paid close attention to, a customer might not notice.  OEM 4100K Bulbs manufactured by Philips has a colorshift of approx 250K after 500 hours, which will bring it to up to 4350K.  Asian manufactured bulbs have been reported to have little or no color shift. Most of them come with output stealing blue filters, which may be part of the cause.


What does the P/N on Philips bulbs mean?

OEM=Original Manufacturer Equipment
Aftermarket=sold as spare bulbs or manufacturer of kit
Bulb base: P32-d
"CM" means color match.

85122: D2S. Color is bluer white with slight greenish tone.
85122+: D2S CM (Plus). 5000K, Aftermarket only. Go to pair up with used 85122.
85122WX: D2S Ultinon 6000K, Aftermarket only. Ultinons label on bulb "Philips BL-2 Non automotive use"
85123: D2S. Color is bluer white with slight purple tone. Not officially on Philips product list. Nevertheless, it is found in some BMW OEM HID headlamps.
85126: D2R.
85126+: D2R CM (Plus). 5000K, Aftermarket only. Go to pair up with used 85126.
85126WX: D2R. Ultinon 6000K, Aftermarket only.
 



The hard facts on 4100K Philips HID bulb:

This is the bulb installed OE in many HID headlamps today. It is 3200lm bright and 4100K colortemp. At zero hours it starts off at 4100K and goes upwards to 4600K after 1500 hours. After that there are no measure points, but curve has the direction to reach 5000K after maybe 2500hours. Do not rush out and buy some 5 year old bulb from an old BMW 750iA yet; As all other bulbs, they also get dimmer with time:
100% at 0 hours
90% at 200 hours
80% at 1000 hours
75% at 1500 hours
70% at 2000 hours
There is no reason to jump any conclusion that they loose lumen too fast. I would be surprised if any other lamp can do better. A halogen lamp is usually out of service after 5-600 on graphs like this. Asian HID bulbs have reputation for 5-600 hours of life as well.


6000K, 7000K, 15000K HID bulb scam!

Many people said, "oh no, not another blue bulb!", and thought that the blue low quality bulb "scam" finally spread over to hit the real HID market in late 2001. Philips Ultinons made in Germany have equal quality, like the OEM Philips bulb, so you cant really call that product a scam.
There are other blue HID bulbs made other places in the world that can be scam products. They maybe even have the Philips or Osram name on the box, or the base, but bulbs are made or modified by someone else. Equal bulbs can also be marketed to have different color temperature. Most customers would never know if color temp was off, as long as they are matched as a pair. Some kit and bulb suppliers advertise with 7000K and higher. This can be suspective because a lower than OEM quality bulb can have been used. No bulb OEM manufacturer makes any versions with more than ~6000K, so either it is 6000K, or the bulb might have been painted. Painting bulbs decreases brightness and in most cases decreases life. So be aware what you are buying.


What are the results of using 6000K, 7000K, 15000K HID bulbs?

Stage 1 refers to 4100K and stage 2 normally refers to something higher value K.
As an example, a 6000K bulb in some headlamps might not show much difference at all, others will look bluer. These are observations when standing in front of the car looking into the headlights from above. After getting over the initial thrill of cooler light, many drivers have noticed that important traffic information are not as apparent as with OEM standard bulb. White traffic signs are being lit too much and can feel glaring.
During winter 2002, exponential use of Kelvin (K) rating is used as brightness improving advertisement. Its all just big empty words, do a search for "Kelvin color temperature" on a search engine (i.e.: yahoo.com) and you will see that it has nothing to do with brightness and all to do with color. Going upwards from 4300K means that your light turns blue at the expense of total brightness and yellow color. Theoretically, if the same brightness were to be kept, you would have to increase the wattage of the bulb from 35 to maybe 40W, and redesign the ballast. This would be a very costly solution, so that’s pretty much why all automotive HID bulbs are 35W.


What brands of HID bulbs is NOT world class

Many sellers nowadays offer several brands with different price tag. Typically, HID bulbs designed and manufactured in simple facilities will have lower quality. Most of these bulbs are made Asia. Typical signs of lower quality are non existing data sheets. The marked also has many copycats: Packaging and bulb labeled Philips or Osram exists on the marked. Be skeptical if a brand name bulb is too cheap to be true. Consumers report life to be short (less than 600 hours) and dim output.  Here is a list of bulbs in this category:

· Vestec

· Bulbs in kits sold by Misterjung

· Bulbs in kits sold under "Bohmen"


Upgrading High / Low Bulbs H4 (9003).

For your Model of bulbs you will have HID low beams and loose your high beams. However If you had hid for your low beams that are 3x brighter than your High Beams you have currently and will never need your high beams anyways.  HID will give you more light output than your high beams currently, so there would be no use for them. 


Will DRL (daytime running lights) or Auto Switch On effect the HID kit?

For vehicles with DRL that use the same bulb for both DRL and low beam you will need to deactivate your DRL. DRL operate on reduced wattage or fluctuating current levels. This will cause the HID system to flicker and burn out prematurely. Please ensure that your OEM headlight harness is providing a constant 12V to ensure that no damage will be caused to the HID system


Is the ballast water and acid proof?

No. It is designed to withstand light mist of non acid water. In order to weatherproof the ballast, it should be mounted in the underhood compartment, rather than in the bumper area or wheelwells. This will ensure that a minimal among of water will reach the ballast. The ballast itself has been weatherproofed to a degree, but it is still best that it not come into contact with large amounts of water. Exposure to a small amount of water will not damage the system.


What determines a good quality ballast?

Good ballast is one that is used by OEM. Examples would be Denso, Valeo, Philips, Hella, Matshushita.


What about automotive lighting parts and unknown vendors on eBay?


Are these XENON HID light systems street legal?

Every jurisdiction has its own rules and regulations governing the use of automotive lighting. XENON HID lighting systems that are supplied with the vehicles from the factory are DOT approved.

NO XENON HID conversion kit available from any source is DOT approved if installed outside of the factory. Moreover, in the U.S, this is not street legal for use on public roads. As a result, we officially endorse the kit for exhibition and off-road use and will only sell the kit to be used for these purposes. We are not responsible for buyers who violate the terms of sale while in which they will assume all responsibilities for any unauthorized or unintended use other than exhibition or off-road use.

Our DOT approved line of HID products are completely street legal and are S.A.E approved.
